Pinpoint Test A : The Adjustable Pedals Only Move In 1 Second Intervals

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

  1. A1 RETRIEVE THE SCCM DTCs

    • Ignition ON.
    • Using a diagnostic scan tool, carry out the SCCM self-test.

    Were DTC B1368:11 or B1386:12 retrieved? 

    Yes  GO to  A2.
    No  If no DTCs were retrieved, CONFIGURE the SCCM using As-Built data. If other SCCM DTCs were retrieved, REFER to the DTC Chart: Steering Column Control Module (SCCM) .
  2. A2 CHECK THE SCCM HALL-EFFECT CIRCUITS FOR A SHORT TO VOLTAGE

    • Ignition OFF.
    • Disconnect adjustable pedal motor C2159 .
    • Disconnect SCCM C226C .
    • Ignition ON.
    • Measure:
      Positive Lead Measurement / Action Negative Lead

      Ground

    Is any voltage present? 

    Yes  REPAIR the circuit.
    No  GO to  A3.
  3. A3 CHECK THE SCCM HALL-EFFECT CIRCUITS FOR A SHORT TO GROUND

    • Ignition OFF.
    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C226C-3

      Ground

    Are the resistances greater than 10, 000 ohms? 

    Yes  GO to  A4.
    No  REPAIR the circuit.
  4. A4 CHECK THE SCCM HALL-EFFECT CIRCUITS FOR AN OPEN

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C226C-3
      GFD134423Courtesy of FORD MOTOR COMPANY
      C2159-3
      C226C-6

      C2159-4

    Are the resistances less than 3 ohms? 

    Yes  GO to  A5.
    No  REPAIR the circuit.
  5. A5 CHECK THE SCCM HALL-EFFECT CIRCUITS FOR A SHORT TOGETHER

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C226C-3
      GFD134423Courtesy of FORD MOTOR COMPANY
      C226C-6

    Is the resistance greater than 10, 000 ohms? 

    Yes  INSTALL a new brake pedal and bracket. REFER to Brake Pedal and Bracket . CLEAR the DTCs. REPEAT the self-test. If DTC B1368:11 or B1368:12 is retrieved again, INSTALL a new SCCM. REFER to Steering Column Switches .
    No  REPAIR the circuit.
